NETE is a prodrug of norethisterone in the body. [13] Upon reaching circulation, it is rapidly converted into norethisterone by esterases.Hence, as a prodrug of norethisterone, NETE has essentially the same effects as norethisterone, acting as a potent progestogen with additional weak androgenic and estrogenic activity (the latter via its metabolite ethinylestradiol). [14]
Norethisterone, as norethisterone acetate and norethisterone enanthate, has been studied for use as a potential male hormonal contraceptive in combination with testosterone in men. [ 124 ] [ 125 ] Long-acting norethisterone microspheres for intramuscular injection have been studied for potential use in birth control.
Norethisterone (17β-deacetyl-NETA), the active form of NETA. NETA is a prodrug of norethisterone in the body. [9] Upon oral ingestion, it is rapidly converted into norethisterone by esterases during intestinal and first-pass hepatic metabolism. [10]
In the process, metabolites, or byproducts, of the drug are produced, which can linger in our blood, urine (and even in our hair) for long after the initial effects of the drug are felt.
The U.S. Food and Drug Administration (FDA) on Thursday approved a new type of prescription pain medication for adults to treat moderate to severe acute pain. The drug, called Journavx ...
[8] [15] [16] There are metabolites of Nandrolone that act as long-lasting prodrugs in the body, [8] such as 5α-Dihydronandrolone. Nandrolone esters were first described and introduced for medical use in the late 1950s. [8] They are among the most widely used anabolic steroid worldwide. [8]

These include the 19-nortestosterone derivatives norethisterone, noretynodrel, and tibolone, as well as the norethisterone prodrugs [251] norethisterone acetate, norethisterone enanthate, lynestrenol, and etynodiol diacetate. [1] The estrogenic activity of norethisterone and its prodrugs are due to metabolism into ethinylestradiol. [1]
